effective means for rapidly deforming these plates so as to assume approximately the contour or outline of the portion of the boat to which it is adapted to be applied, thereby enablin said plates to be expeditiously assemblef without liability 0 buckling or other distortion.

A further object is to enable each plate to be thus deformed throughout its entire len h in a single 0 eration.

ther objects an uses will appear in the following description:

In the drawing; Figure l is a side elevation of a metal press showing my invention as applied thereto for deforming the plates. Fig. 2 is an enlarged transverse vertical sectional view of a portion of the sliding carria for supporting the yielding bed plate, an also showing in section a portion of the deforming roller coa-cting with said plate. Fi 3 is a side elevation of the detached ro er and its supporting yoke showing a portion of the underlying yielding bed and its supporting plate.

The invention consists primarily in the use of an elongated flat resilient bed plate -1 and a pressure roller -2-, one of which parts, as the bed plate 1, is adapted to be moved lengthwise relatively to the other part, the bed plate 1 being preferably made of pliable rubber or of alternate layers of rubber and canvas, such as-is commonly used for packing, although rubber belting may be equall efficient, said resilient plate being mounte in this instance upon a stiff underlyingbacking 3, which in this instance is at least coextensive with, if not of greater area than, the plate 1 so as to support the resilient bed at all points throughout its area and is mounted upon, and preferably secured to, a reciprocatory the plate, as a sliding carriage 4 of an iron laner -5-. This planer is provided wit the usual upright guideway' or bracket -6- upon which is mounted a vertically movable tool-head -7--, to which is secured the sup- Patented June so, 1909. i

porting yoke, as -8, for the pressure roller -2.

The yielding or resilient bed late -1- may be of any desired width or ength, and is adapted to support upon its upper surface which is to be deformed, the surface area of the bed plate -1- depending somewhat upon the dimensions of the plate a. This plate a is first cut to the desired outline according to the position which it is to'assume on the boat, and is laid flatwis'e upon the resilient bed plate f -1, after which the roller --2-- is adjust ed by the usual means for adjusting the toolhead 7 for pressing the roller 2 with sufiicient force against the upper face of the plate a to depress the underlying portions of the latter 1nto the upper surface of the yielding bed plate 1, it. being understood that the latter yields under such pressure. In the present instance I have shown the face of the roller -2 as curved or convexed transversely, so that when it is firmly pressed against the surface of said late, the portion in contact with the roller w be correspondingly concaved so that when the plate a has been traversed by the roller -2- it will assume a cross sectional conca-vo-convex form and will also assume a similar but less exaggerated lengthwise concavo-convex form, the degree of curvature of the plate depending somewhat upon the radius of the arc of the face of the roller, and also upon the degree of pressure with which the roller is forced against the plate, and it is clearly evident that this transverse and lengthwise curvature of the plate may be varied at differentpoints in its length during the deforming process by simply increasing or diminishing the pressure of the roller therecarriage movable back and forth relatively to the pressure roller -2-, it is evident that the invention contemplates any reversal of action and also variation in the degree of transverse Curvature in the face of the roller to give varying deformations to the plate j operated upon.

In operation the late to be deformed is laced upon the yiel ding rubber bed 1- twise and moved with the carriage under the pressure roller 2, the latter being pressed with the desired degree of force against the surface of the plate, thereby flexing or depressing the underlying portion of the yielding bed, which, together with the pressure of the roller, produces the desired curvature or deformation, the degree of such deformation being regulated by the degree of pressure exerted by the pressure roller '2, and thispressure maybe varied at will during the'movement of the carriage to give greater or less curvature to the plate at diferent 'points as may be necessary.

What I claim is '1. In a deformin device for sheet metal plates, :1 flat elastic is mounted, a still backing underlying said elastic bed a pressure roller for pressingthe' upon which the plate r plate against the bed, and means for moving one of the parts relatively to the other.

2. In an apparatus for deforming sheet metal plates, an elastic bed and movable carriage therefor having a stifi' flat backing for the elastic bed, and a pressure roller adjustable toward and from the bed for depressing the portion of the plate en aged by the roller.

3. In a device for de orming flat sheet metal plates, an elastic bed having a flat upper face, a supporting carriage for the elastic bed having a stifi flat backln engagingthe under side of the bed direct y under the roller, and a pressure roller having a transverselv curved presser face.

t. In a device for deforming sheet metal plates, a--flat elastic bed for supporting the plate to be deformed, a movable carriage having a stiff flat bacln'n for the bed, and a roller having a convex ace adapted to engage the plate on the bed, said roller being ad ustable toward and from the bed.

In witness whereof I havehe'reunto set my hand this 8 day of March 1909.
